AUTOMATIC WEATHER-STRIP.

To all whom it may concern.

Be it known that we, WILLIAM J. DILLARD and JOHN D. TAYLOR, citizens of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Automatic eather Strips; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in automatic weather strips for doors; either sliding or swinging, and it consists of a simple and eflicient device of this nature, so arranged that as the door is closed, the joint intermediate the bottom of the door and the floor will be made air and storm tight.

The invention is clearly illustrated in the accompanying drawings, forming a part of this specification, which will be hereinafter more fully described, and in which drawings-- Figure 1 is an elevation with parts broken away.

Fig. 2 is a detail top plan view of an insert against which the weather strip bears.

Fig. 3 is a detail vertical sectional view through the door and resilient strip in the sill.

Fig. 4 is a detail in elevation of an attachment to the door jamb.

Figs. 5 and 6 are detailed views.

Reference now being had to the details of the drawings by letter; A designates a casing of any suitable construction and mate rial, which is inserted in a recess formed transversely in the bottom of the door. Said casing has a projecting portion 2 at one end, which is fastened to the edge of the door.

Mounted to have a vertical movement within said casing, is a blade 3 of metal,

which extends the width of the door and is adapted to be given a downward movement, so that its lower edge will project beyond the bottom of the casing when the door is closed.

A plunger 4 is mounted in suitable bear- Specification of Letters Patent.

Application filed December 10, 1919. Serial No. 343,765.

the hook portion of a hook-shaped member I 5 mounted to tilt upon the fulcrum pin 6 passing through the base of said hook portlon, said lever being in turn pivoted to an upwardly projecting integral portion of the blade 3.

A coiled spring 7 is mounted upon the plunger, and one end bears against the end of a recess 8 in the top of the casing and its other end is fastened to the plunger, the purpose of said spring being to normally hold the plate retracted within the casing and the plunger at its farthest outer limit.

An adjusting thimble 9, interiorly threaded fits the threaded end of the plunger and is moved in. an aperture in the upwardly pro ecting portion of the casing. Said thimble may be held in different positions upon the forward part of the plunger according as it may be desired to regulate the throw of the blade. Said thimble projects through the rear edge of the door and is adapted, when the door is closed, to contact with the j amb of the door to impart a longitudinalmovement to the plunger.

A plate 11 is fastened to the jamb, against whic the thimble is adapted to contact, and which is provided for the purpose of pre' venting the thimble marring the door jamb as the door is opened and closed.

Fitted in a groove formed in the sill or floor of the door, immediately underneath the casing, is a channeled member 12 with flanges 13, the upper surfaces of which are flush with the floor.

A strip of rubber, or other resilient material, is mounted in said recessed member and against which the blade is adapted to impinge as it is thrown downward in the act of closing the door, thus making a tight. storm-proof joint intermediate the floor and the sill underneath.

By the provision of an automatically operated weather strip made in accordance with my invention, it will be noted that a simple and efficientmeans is provided, and so arranged that when the door is closed, the blade will be automatically thrown down, making a tight joint, and preventing'air, water and snow passing through between the door and the floor. When the door is opened, the various parts will return to their normal positions, permitting the door to swing freely without interference.

VVh-at we claim to be new is: V

In an automatic weather-stripstructure, a

blade carried by the door and movable downward by the closing of the door, a.slot

in the sill of the door frame adapted to receive said blade and a resilient filling for said slot, the upper surface of filling normally co-planar with the top of the sill. 10

In testimony whereof we hereunto afiix our signatures.
